Hello All,

I'm about to replace my 80 series plastic radiator (which has cracked), should I have a genuine Toyota plastic one. Or opt for a new aftermarket brass one?
Which do you think would give the best service? and be most reliable?

Go for the aftermarket brass one.
Proper annual maintainence of your cooling system is a must if you want to get good life out of your vehicle. The ethylene glycol coolant should be changed at least every 18 months MAX. What happens to this coolant that after this time, the coolant starts to go acidic like viniger and actually gets corrosive. When you replace it, you need to use one of the major brands of concentrate like Mobil (my personal preferance) or Shell, Caltex etc. and get the deionised water from the supermarket to dilute to the recomended dilution.

ALL fluids should be changed in the vehicle at a max 18 months. THis includes flushing all the master cylinder and each wheel cylinder till the new brake fluid comes through. You will be amazed at how dirty and contaminated the brake fluid will be. The power steering fluid, transfer case, clutch master cylinder (if fitted) gear box, diffs etc. etc. This is the only way you will ensure a trouble free run and save on repairs.

If you want to the correct lubrication advice for your vehicle, grab your local phone book and look up Mobil and their 1800 LubeLine phone number. They will either fax or mail the correct lubrication products for your vehicle. I run in the majority synthetic oil and keep strictly to the Mobil recomendations and have done for nearly 30 years and never had any major breakdowns or expensive repair bills.

Hi Oziexplorer.
Change the oil in the power steering? Sounds like a sensible thing to do but as I recall that is not mentioned in my service manuals and I do not know of any drain plug so fitted. Perhaps you can enlighten me.

I own a 75 Series Troopie.

Incidentally, when it rains I put out a couple of buckets and over the winter period I collect over 6x20 litre plastic containers full of good rain water. More than enough.

Janset I have no idea on a Toyota, I have never personally owned one.

I now use Mobil synthetic in the power steering, after being recommended by two different people who re-build power steering pumps and racks. The one guy said to me, that if you use the synthetic from one of the major manufacturers and change it like I do annually, you would probably never have to touch your power steering pump and rack for the life of the vehicle.

The regime of changing all the fluids annually, is without a doubt the cheapest and best maintenance you can do. In all the years I have been doing it, I have never had any problems with cooling, brakes, clutch cylinders etc. etc.

Plastic is always cheap in my opinion, and a plastic radiator(i have read your post 12 times so far and cant believe my eyes!)????

Go with something solid... I just had a new 3 core put in the GQ, it now holds more coolant as well which is always a good thing...

Plastic radiator... what next, plastic pistons?? sheesh..

(I just read it again to see if I should cut out the diet pepsi from my diet).....

Like Truckster...I'm at a loss re plastic radiators. I can't see how they can transfer heat effectively. I didn't even know they existed!'s likely the metal aftermarket radiator will probably be cheaper than the Toyota original. The heat transfer would have to be more efficient too. So I know where I'd putting my money!

By plastic, I assume you refer to the ally core with plastic tanks type of original. Anyway, I had the same snag with my Bravo a few years back - it had the ally/plastic unit also - went to the radiator specialist who put in a DOUBLE CORE all brass type - better cooling - cheaper too. Has been a winner - new owner (close family) is still getting good service a few years down the track. .....dp
